Inventor: KANEHARA MIKIO
IPC: C01F7/02
Filed: 1983-06-03
Abstract: PURPOSE:To subject an organic substance in a sodium aluminate solution to oxidative destruction efficiently, and to remove it easily, by treating the solution prepared by Bayer's process with an oxidizing gas having a dew point higher than the temperature of the solution. CONSTITUTION:In preparation of alumina by Bayer's process, a sodium aluminate solution circulating in the process is sealed in a pressure container, steam is added to an oxidizing gas such as oxygen or an oxygen-containing gas, e.g., air, etc., the dew point of the gas is made higher than the circulating mother liquor, and the gas is introduced to the pressure container by pressure. By this treatment, an organic substance contained in the solution is efficiently decomposed, finally processed into oxalate, carbonate, etc., and exhausted easily form Bayer's process to the outside of the system, and total amounts of organic substances can be reduced.

Title: Optical recording medium
Inventor: SUZUKI KATSUMI
IPC: G11B7/241
Filed: 1986-04-30
Abstract: PURPOSE:To prevent the exfoliation of the laminated part between an org. material and inorg. material and to prevent the cracking of a thin inorg. film by interposing an adhesive layer consisting of the org. material and org.-inorg. intermediate region layer between an org. resin substrate and the thin inorg. film. CONSTITUTION:This optical recording medium is formed by successively laminating the org. resin substrate 3, the adhesive layer 9 consisting of the org. material, the org.-inorg. intermediate region layer 11, the thin inorg. film 7a, the recording film 5, etc. More specifically, the adhesive layer 9 consisting of the org. material and the org.-inorg. intermediate region layer 11 are interposed between the org. resin substrate 3 and the thin inorg. film 7a. The adhesiveness in the laminated part between the org. material and the inorg. material is thereby improved and the difference in the coefft. of thermal expansion between the adhesive layer formed of the org. material and the thin inorg. film and thermal strain are absorbed by the org.-inorg. intermediate region layer. The exfoliation of the laminated part between the org. material and the inorg. material and the cracking of the thin inorg. film are thus prevented.

Filed: 1984-05-18
Abstract: PURPOSE:To reduce purity drift due to the shadow mask doming by fixing metal plates to the fixed regions of the shadow mask so as not to obstruct the electron beams passing through the electron beam through holes. CONSTITUTION:The metal plates 11 shown by oblique lines having the openings not obstructing the electron beams passing through the electron beam through holes 5 are fixed to the regions likely to generate partial purity drift of a shadow mask 2, namely to the regions having the width W and the length L from the places separated from the ends of the shadow mask 2 by the distance D by thermal welding of frit glass powder. Thereby, as the strength of the shadow mask 2 is heightened, thermal capacity increases with the additional metal plates 11 while lowering thermal conductivity with frit glass 12 thus to enable to decrease thermal expansion speed of the shadow mask 2 by hitting of electron beams while extremely miminising the doming of the shadow mask 2.

Title: Recording method of enlarged image
Inventor: KOMIYAMA KIYOSHI
IPC: B41J2/485
Filed: 1989-04-20
Abstract: PURPOSE:To record an enlarged image of the size outside a fixed form by a method whereby not smaller than half a document is read from each confronting edge thereof and recorded on an enlarged scale, and the two recorded materials are bonded while the overlapped images are piled. CONSTITUTION:A document 4 of A4 size is set in a widthwise direction at a document entrance, and the scanning area is set larger than A5 size. As the document is scanned in this state, an area A not smaller than half the document 4 is read out for the first scanning period (a). The read image signal is multiplied N times through signal processing, so that the reading area A is recorded on an enlarged scale onto a recording paper 6 of A1 size by the enlarged image signal. Thereafter, when the document 4 is turned and inserted in a widthwise direction at the document entrance, a reading area B is recorded on an enlarged scale onto a recording paper 6 of A1 size in the similar manner as above. While the overlapping portions of the two recording papers 6 are piled, the recording papers 6 are bonded. Accordingly, even if the maximum size a copying apparatus can afford to magnify and record is A1, it becomes possible to record a document on an enlarged A0 size.

CONSTITUTION:Distance l1 of an electromagnetic-wave attenuating bar 4 from the central axis 0 shall be more than such size (l1>=2a) which does not attenuate the helix mode, l2 shall be such size when it is fixed structurally to a metallic vacuum enclosure 3. The electromagnetic-wave attenuating bar 4 is most effective to be disposed over the entire slow-wave circuit. The electromagnetic- wave attenuating bar 4 shall be a dielectric having such specific dielectric constant which is larger than that of the dielectric holding bar 2 in order to give a large attenuating effect to the coaxial mode and said bar 4 forces the electric field of the coaxial mode to be centralized. For instance, beryllia is used as the dielectric holding bar 2, and porous alumina impregnated with electromagnetic-wave attenuating substance is used as the electromagnetic-wave attenuating bar 4.

Abstract: PURPOSE: To maintain a driving torque of liquid for a specified time after power is turned off, with respect to an induction solenoid pump for use in power plants. CONSTITUTION: Exciting coils 1 are wound around a duct that conveys liquid in an induction solenoid pump. A rotating magnetic field 13 is generated by excitation, and a driving torque is produced in liquid by means of the magnetic field and eddy current induced in the liquid. The exciting coils 1 are connected with a capacitor 10 for excitation. Provided with a voltage E from a power supply 11, an oscillation circuit composed of the exciting coils 1 and the capacitor 10, produces sinusoidally oscillating waves and generates a rotating magnetic field. When power is turned off, the sinusoidal oscillation is turned into attenuated oscillation, which is maintained for a specified time. Thus the driving torque is similarly maintained.
